【正文】 sed on the Internet is in English and it is the language we used in our daily life. As we all know, when we learn a foreign language, we can master the target language only if we grasp the newest and truest words of it. Making use of networks can appropriately give students enough opportunities to practice English. MotivationAs the famous saying goes, interest is the best teacher. Computer is good for motivating students to study English because it enables the teacher to prepare an interesting class easier, faster and more convenient than before by using the innumerable resources from the internet. Although the initial appeal of multimedia is almost certainly due to its novelty, teachers and learners soon discover other aspects which are more educationally significant. A rich media environment allows contextualization of the target language in simulations which learners recognize as having practical reallife applications. The variety of activities, coupled with the rapid feedback that multimedia provides, also help maintain learner interest and attention. Children are anxious to operate puters because they are associated with fun and games or because they are considered to be fashionable. Many students are tired of traditional English classes and are interested in a new style of learning. When they watch the funny teaching course wares and interact with it, they feel that they can master English. They can study English with their own learning styles, and they can see the results of their learning. Students think materials are new and fresh if they are presented on puters. They seem to be willing to spend more hours and do more exercises on a puter than by hand (Kital, 1993c). Individualization One problem in English teaching is that students have a variety of interests and levels of English proficiency. Their learning speeds and learning styles also vary. CAI can help teachers to help individual students meet their own needs at their own pace. Shy or inhibited students can greatly benefit from individualized, studentcentered learning. I believe that this is one of the most important reasons to use CAI. In our daily teaching most teachers prefer to care the top students and those noisy students and at the same time neglect the ordinary and shy students. As a result those students will lose their interest in learning English for always lack of the teachers’ notice and it will make the English class increasingly difficult to carry on. However, CAI enables the students to study according to their own pace and level, and they can get the evaluation immediately after their operation and they could choose the part they wish to study and have the freedom and right to decide when they move to the next part. Students are happy with even partially individualized instruction, and it is more effective than traditional teaching. Greater Interaction For learners using multimedia, it is the interactive element that brings them control over the learning environment. Contrary to the traditional classroom, child is the star through the learning by using the multimedia. Presently, there are many welldesigned and suitable web sites apply the resources that can be used by the children. Such as ,~iteslj/links/ESL/Games/ ,or , interactivity allows the children to select the materials they need to work with, the order in which they want to work through those materials, and the pace they want to work at. Interactivity also provides the learner with the help, guidance and feedback needed for a successful learning experience. Some learning pages are also designed so that learners must successfully plete activities in order to progress. This encourages active engagement with materials. Furthermore, Random access to web pages breaks the linear flow of instruction. By sending Email and joining newsgroups, EFL students can municate with people they have never met. They can also interact with their own classmates. Furthermore, some Internet activities give students positive and negative feedback by automatically correcting their online exercises. They bee the creators not just the receivers of knowledge.3. The Problems in CAI and the Countermeasure Although using CAI in primary school English teaching has many advantages, it is not so ideal without any shortage. Even though teachers use puters more and more in their daily teaching activities, there are still many misunderstandings about puters and CAI. As we are considering how to improve our CAI, we should doubtlessly think about how to solve these problems. Should the puter dominant the classroom?Using puters in English teaching is the latest trend and is thought to be fashionable, but we have to admit that the puter can only play an assistant role in the classroom, the students and the teacher should play the main role in our daily English lessons. We can see that some teachers misunderstand the concept of CAI，and within the 40 minutes class, there is no one word on the blackboard and the popular language in those classes are,” please look at the screen.”. In those English lessons, the teachers have changed their roles into the puter operators and the course ware designers. We have to realize clearly that there is no one else can be more important in the classroom than people. Financial BarriersFor most of the rural area in Beijing, the economy is paratively backward than the urban area. As a result, the education in those parts is slower and harder because of lacking money and necessary equipments. Although the teachers could use the puter in classroom now and the students could also use the puters sometimes at school, but for most children don’t have puters at home, it is impossible to ask all the children to work online after school. In order to solve this problem, we could set some English tasks and then apply more chances for the children to find the answer and fulfill their tasks by surfing the Internet at school.
